I7 2630QM malfunctioning ??

[sdaoud]

Alright so my problem all started with an over heating issue as many issues with cpus do. I have taken steps to resolve this issue by replacing the fan twice, putting new silver5 thermal past on and keeping the interior of the laptop as clean as possible with no heat exhaust blockage, but the overheating issue is still there. I am fairly certain the heating issue is caused by a design flaw so I'm not here about the heat. I am here because I think the heat caused some damage to my cpu or other parts because my clock speed is a very low 700mhz and fails the intel diagnostics tool every time due to frequency speed. I have done some tests and found that I could bypass the throttling of my computer with throttlestop, which causes cpuz to show a significant increase in speed to around 2000-2900mhz, but my computer is still slow, and when running the intel diagnostic tool my computer still fails the frequency test saying it is running at a slow 300-700mhz when throttlestop, cpuz and intel extreme tuning utility all say I am running around 2000mhz. So I don't know what is going on, I need some help in getting my computer to run faster, I can deal with the heat with some external fans but I can't deal with how slow it is running.


running throttlestop does increase my computers performance speed a bit but no where near what it should be. Is there different clock speeds ? could one program be reading one speed while another is reading a different one ? How can I get my computer to pass the intel diagnostic test ?


this is my computer btw:

THANK YOU ALL

CPU-Z:
I would expect this to be accurate. Mine shows both the voltage and frequency changing.

CORE TEMP:
An excellent program to monitor the temp of all CPU cores.

Intel Processor Diagnostic Tool:
https://downloadcenter.intel.com/confirm.aspx?httpDown=http://downloadmirror.intel.com/19792/eng/IPDT_Installer_2.8.0.0-1_x86_2.10.0.0.MP-1_x64.exe&Lang=eng&Dwnldid=19792

*I guess this isn't the same tool because it shows no frequency at all, just runs tests. Might want to run it though.

Other:
Your CPU should throttle itself at the hardware level if it got into a danger zone for temperature. If your CPU had been damaged I'd expect BSOD on bootup with some sort of processor related error or crash even before it could display the error.

The CPU will also vary its frequency and voltage normally to save power so when not stressed it might be running at 700MHz. For example, if you opened CPU-Z it might sit around there and jump up and down (along with the voltage) a bit but under load like Prime95 or an Intel stress test it should sit at the max Turbo it can do.

???
It's unclear to me why you thought it was overheating in the first place, and if you still think it is. Is it possible you've never even had a real problem?

My cpu throttles itself even when I am trying to do a resource intensive task, also my computer idles around 80 degrees F and has shut off multiple times in the past due to over heating, but again I can deal with the other heating I just can't deal with how slow it is working.

the intel diagnostic tool you linked me to is the same one I used and does do a frequency test as shown here:

http://tinypic.com/r/jpemub/8

that is my failed test, I can read the results of the test by going to file>test results and read what frequency it clocked my computer at, which has been really low even though cpuz shows it running at around 2000mhz (again only if I bypass the throttle with throttlestop, otherwise it sticks to around 800mhz)

But lets humor the notion that it isn't my cpu that is the issue, what else could be causing my machine to slow down so significantly?

The Core Speed that CPU-Z reports is a meaningless number when a CPU is throttling internally. Before trusting any monitoring software, why not see if it can pass both of these tests?

Here is a Core i7-4700MQ running the Super Pi Mod 1M benchmark. It has taken 9.910 seconds to complete the first 19 loops of the calculation. I think that's a reasonable time for a properly running 4700MQ. CPU-Z reports that the CPU is running at 3495 MHz.

There are 2 types of throttling that are used in most laptops. Intel designed these so a CPU could be quickly cooled down but unfortunately, some manufacturers have decided to overuse throttling. The two main types are clock modulation throttling as well as chipset clock modulation throttling. Either or both of these can be used and they will instantly kill performance when they are engaged. ThrottleStop is the only tool I know of that can detect and report both types of throttling.

If you look at the above screenshot, ThrottleStop reports both types of throttling are at 100.0% which means the CPU is being allowed to run at its full rated speed.

In the second example, the same calculation as above has taken 1 minute 33.599 seconds or 93.599 seconds.

That is over 9 times longer. CPU-Z shows 3391 MHz. The CPU is severely throttling and CPU-Z barely reports any difference. ThrottleStop correctly shows that each thread of the CPU is using Clock Modulation throttling and each thread is running at only 12.5% of its rated speed. The C0% is another warning that the CPU is not running as it should.

The next example shows what is reported when an Intel CPU is being throttled with Chipset Clock Modulation throttling.

Once again a calculation that should take less than 10 seconds has taken 93.199 seconds. Serious throttling is in progress and CPU-Z reports 3491 MHz.

Why does the user community depend on CPU-Z if it cannot tell you whether your CPU is running at full speed or if your CPU is being throttled to death?

Turn CPU-Z off. When a CPU is throttling, it is not the tool for the job.

Besides throttling, some laptops also use the bi-directional processor hot (BD PROCHOT) signal path. This allows sensors on your motherboard to signal your CPU and trick the CPU into thinking it is too hot. When this happens, the CPU responds by dropping the CPU speed down to approximately 800 MHz. If a sensor has gone bad, the only way to properly fix this is with a new motherboard. If the warranty is up then I would suggest using ThrottleStop to disable BD PROCHOT. This prevents these external messages from getting to the CPU. When BD PROCHOT is disabled, the CPU will still be able to throttle if it ever gets too hot.

Use ThrottleStop to disable all of the various throttling problems that your laptop manufacturer has saddled your laptop with and rerun the Intel Diagnostic tool. You should see the green flag after that.
